How to detect international mobile phone numbers in batches? Identify valid numbers and empty number status with one click

In cross-border marketing, overseas social traffic, account registration and batch communication scenarios,International number detectionis a crucial step. Unverified numbers may be empty numbers, cold numbers, or invalid numbers that have been banned. Once put into use, not only will the conversion rate be low, but sending costs will be wasted, and even the security of the platform account will be affected. Therefore, many companies regard international number detection as a top priority.

1. What are the core dimensions included in international number detection?

In practical applications, international number detection is more than justSimple judgment of "active" and "inactive". A complete detection process often needs to cover the following dimensions:

Is the number format compliant?: Many country numbers have complex structures. Determining whether the first digit is the country code and whether the length is accurate is the first step.

Whether the number has been registered on the platform:likeThe registration status of WhatsApp, Telegram, LINE, Zalo, Signal and other platforms affects the accuracy of subsequent delivery.

Whether the number is empty or cold: Although some numbers are in compliance with the format, they have been deactivated or have no owners and need to be cleared in batches.

Is it currently online or powered on?: Especially suitable for real-time touch-based businesses, such as social group building, customer service invitations, etc.

Is it a virtual operator orVOIP number segment: Some countries have a large number ofVOIP number segment, this type of number is easily judged as a low-trust number on some platforms.

2. Common application scenarios for international number detection

1.Screening before raising an account on a cross-border social platform

When companies operate overseas account matrix, they usually use local numbers to register. After passing the test, numbers with a high registration success rate can be used first.

2.Exclude empty accounts before sending WhatsApp/Telegram marketing groups

Before sending mass marketing messages, checking whether the number is actually registered on the relevant platform can greatly reduce the risk of failure to send and account suspension.

3.Outbound call robot/Pre-cleaning voice notifications before delivery

The voice robot system can significantly improve the call completion rate and call efficiency by detecting and eliminating powered-off or invalid numbers.

4.Status recognition before users join a group or automatically add friends

Determining the online status of a user's number can improve the interaction rate and conversion effect in private domain operations.

4. Things to note during the international number detection process

1.Data compliance issues in different countries

Before conducting number detection, it is necessary to clarify the privacy policies of the country where you are located and the target country, and follow the bottom line of legal and compliant use of data.

2.Frequent detection may trigger platform risk control

Some platforms such asWhatsApp will restrict the behavior of frequently querying registration status, and it is recommended to use low-frequency API or periodic polling mechanism.

3.More effective when combined with behavioral data

Merely detecting the number registration status is not enough. Coordinating user behavior (last active time, communication frequency, etc.) will be more conducive to subsequent accurate contact.
